for operations such as removal of frameworks, prestress, or cracking control.This paper presents the development and evaluation
of a potential active wireless USB sensing tool that consists of a miniaturized electromechanical impedance measuring chip and a
reusable piezoelectric transducer appropriately installed in a Teflon-based enclosure tomonitor the concrete strength development
at early ages and initial hydration states. In this study, the changes of the measured electromechanical impedance signatures
as obtained by using the proposed sensing system during the whole early-age concrete hydration process are experimentally
investigated. It is found that the proposed electromechanical impedance (EMI) sensing system associated with a properly defined
statistical indexwhich evaluates the rate of concrete strength development is very sensitive to the strength gain of concrete structures
from their earliest stages.http://creativecommons.org/licenses/by/4.0/Smart Materials Research2013
